water content of natural gas

Liquid water is removed by gas-liquid and liquid-liquid separation.

The capacity of a gas stream to hold water vapor is:

A function of the gas composition Affected by the pressure and temperature
of the gas Reduced as the gas stream is compressed or cooled.

When a gas has absorbed the limit of its water holding capacity for a specific pressure and temperature, it is said to be saturated or at its dew point.

Any additional water added at the saturation point will not vaporize, but will fall out as free liquid.

If the pressure is increased and/or the temperature decreased, the capacity of the gas to hold water will decrease, and some of the water vapor will condense
and drop out.
